推荐答案

HttpWebRequest 实际上会默认使用 IE 代理设置.

HttpWebRequest will actually use the IE proxy settings by default.

如果您不想使用它们，您必须专门将 .Proxy 属性覆盖为 null(无代理)或您选择的代理设置.

If you don't want to use them, you have to specifically override the .Proxy proprty to either null (no proxy), or the proxy settings of you choice.

 HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://news.bbc.co.uk");
 //request.Proxy = null; // uncomment this to bypass the default (IE) proxy settings
 HttpWebResponse response = (HttpWebResponse)request.GetResponse();

 Console.WriteLine("Done - press return");
 Console.ReadLine();
